Introducing the Trinity Three Stone Princess Cut Engagement Ring

The Trinity engagement ring dazzles with graduating sizes of Princess cut diamonds. Flowing effortlessly from a slim, court shaped band, three perfectly matched square Princess cut diamonds rise in harmony within elegant claw settings. Created in a range of carat weight options each commission is crafted around your requirements and budget—offered in a choice of precious metal options. Our standard diamond colour and clarity (G SI1) ensure whiteness and brilliance from expertly matched diamonds. Contact us for alternative options for additional colour and clarity grades. Each commission takes between three and four weeks—completed with a mirror polish and elegantly boxed in luxury packaging.

Australian clients can now order Fairtrade Gold

Fairtrade Gold is now available for all clients in Australia. If you are interested in commissioning your engagement ring or item of jewellery in Fairtrade Gold, we now have a 100% ethical, traceable precious metal that gives back to small artisanal miners in some of the most impoverished regions of the world. As licensees with the Fairtrade Foundation, we can create most items in this responsibly sourced precious metal in both Fairtrade 18ct White Gold and Yellow Gold.

We are affiliated with the Gemmological Institute of Australia and work to a strict code of conducts. All purchases are backed by a lifetime warranty and most items are delivered with 60 days returns for your total reassurance.

A Note on Diamond Cut Grade

One of the questions we are asked frequently relates to the cut grade of our diamonds. Australian clients are particularly interested in purchasing a beautifully cut diamond. For this reason we set our minimum cut grade standard at "VERY GOOD" to ensure maximum brilliance, fire and scintillation. Where applicable this cut grade will be evident on accompanying certification alongside other details including carat weight, colour and clarity. For certification we favour GIA amongst some of the World's most respected diamond grading laboratories.
